Help Me, Please!

Okay, here’s the task. Come up with some vegetable or food that starts with the letter ‚I‘. The word has to be an English word.

I’m asking because today at work one of my co-workers told me that she had to some homework for her English course that included finding words from a specific ‚group‘ that started with the letters of her name. I don’t know what other categories there were, but I know that she had to find some food or vegetable starting with an ‚I‘. And she couldn’t find one. Neither could the teacher, which – for all I know – is a native speaker.

So I wonder: is there no food or vegetable starting with an ‚I‘? Or are we all just too stupid and/or illiterate.
Can you help?

PS: I don’t think terms like ‚Indian curry‘ count. But I’m open for all suggestions.
